By using these concepts, numbers of necessary and sufficient conditions are established for a nonsmooth variational problem wherein Clarke’s generalized gradient is used. Also, weak, strong and converse duality are established. }, journal = {International Journal of Mathematical and Computational Sciences}, volume = {7}, number = {1}, year = {2013}, pages = {112 - 118}, ee = {https://publications.waset.org/pdf/16970}, url = {https://publications.waset.org/vol/73}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 73, 2013}, }
